My. invention is an improvement in loom harness stop motion and consists in certain novel constructions and combinations of i. parts-hereinafter described and claimed. The object of the invention is toprovide a n1echan1sm to be usedin connection with a warp stop motion mechanism, to operate said mechanism by the dropping of a har-' ness, from the breaking of asupporting i strap, hook, wire or jack.

-tached from the loom. Fig. 3 is an end View of-the improvement with the harness in position, and Fig. 1 is a similar view of a u modified form.

. The present embodiment of my invention comprises a base 1, provided with an open cut-away, an

2 therethrough whereby it may be secured to the floor, the base being provided with an upright 3, having one slde thereof provided'with a slot for rethe bolts 4.

. A bracket comprising a vertical portion 5 and a horizontal portion 6' to be presently described, is connected with the upright, the vertical portion being provided at its lower end with a slot 7, for receiving the bolts 1,

and with a shoulder 8, 410

for engaging the top of the upright, the parts being secured in place by nuts9. t 1

The horizontal portion 6, is in the shape ofa T, and one endof the T is extensible consisting of two sections,one of the sections 10 being provided with a recess for'recciving the end of the othersectionll, and Trboth-of the sections are provided wlthslots 12, through which pass bolts 13, adjustably gsecuringthe parts together. The endsof the I.1d, 15,:the lug 14 having a transverse slot therethrough, for receiving the end of a horizontal portion are provided with lugs spring plate 16, thesaid plate being provldediwith a plurality of perforations 17,

18, which traverses the lug and one ofthe openings for securing the spring in place. The other lug 15 is provided with an open- 111g 19, through which passes the free end portion of the spring plate, and the said lug is extended below the horizontal portion to form a bearing-20, in which is journaled an elbow lever, one of the arms22 of the elbow lever being normally in engagement with the spring plate as shown in Fig. 2. The elbow lever is adjustable in length, comprisingthree sections 21, 21*, 21 the said sections being connected by slip joints 21, as shown in Fig. 2.

The brackets 5, are arranged preferably one at each side of the loom, longitudinally which is supported by the usual straps 24.

As shown in Fig. 1, one of the brackets is secured directly to the side of the loom, as at 25, an adjustable joint 26 being interposed in the length of the bracket.

- It will be evident from the description, that should a strap 24 break as shown at 27, in Fig. 1, permitting one end 23*, of a harness to drop, the said harness 23, as shown in Fig. 3 will engage the spring plate, depressing the free endithereof, and swinging the elbow lever into the position shown in dotted lines in Fig. 3, thus interposi'ng. the free end 21 thereof, between the vibrating feeler 28 of the warp-stop-motion, and the flat bars 29, 30, which guide the drop members 31, which are longitudinally slotted as at 32, to receive the warp threads33.

The feeler 28 is vibrated by any suitable mechanism and when impeded in its free rocking movement by the interposition of a drop member, or the free end of the elbow lever, a hunter connected therewith,.is held in the path of and is engaged by a'tappet camnot shown, which through suitable mechanism releases the shipping lever stop- .ping the loom.

Since the warp stop -motion forms no further describe the same.

In Fig. 4. the bracket 5 is provided at each end of the horizontalportion 6 with lugs 40, to one of which is secured one endof the spring plate 11,.by means of a screw 42, the spring plate being arranged beneath the harness 23. The free end of the spring plate is provided with an opening through which passes'a link 4.3, the end thereof being parts of the invention it is not necessary to.

a horizontal portion arranged beneath the provided with a head 44, and the other end of the link is pivoted to one arm 45 of a rock lever journaled to a bracket 46, the free the guide bar 30.

- Itwill be evident from the description of the constructions of the brackets 5, and the elbow 1ever,'that the attachment.- may be ad- 7 jnsted to different sized looms, and may be used with different forms of warp-stop-motions, being applicable to any type of warp- I claim:

- stop-motion, making use of a movable. feeler.

1. In a loom, the combination with the harnesses, and the vibrating feeler of the warp-stop-motion, of a bracket compr slng harness and provided at each end with a lug, one of said lugs being slotted, and the other provided with an opening, aspring plate having one end adjustably secured in the slot, and the other projecting through the opening, said plate being directly below the harness, an elbow lever journaled adjacent to thelug, provided with the opening,

one end of said lever being normally in-con-- 'tact with the lower surface of the spring plate, and the other being arranged adjacent to the feeler of the warp-stop-motion, and adapted to be interposed in the path of movement of said feeler when the spring plate is depressed.
